PAPER-FOLDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 349,322, dated September 21, 1886.

Serial No. 179,376. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE W. SHAMP, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Paper-Folding Machines;

and I do hereby declare the following to be a.

full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates particularly to certain improvements in a paper-folding machine for which Letters Patent No. 303, 255 were granted, August 12, 1884, to Frederick G. Beach. The construction covered by such patent involved the combination, with a series of folding-flies, of a knife and cylinders, and also oscillating blades, combined with folding-flies for creasing the sheets preparatory to folding same. My improvements upon these constructions, 2 together with other improved details, will be more fully hereinafter described and claimed. In the drawings, Figure 1 is a top plan view of my improved folding-machine. Fig. 2 is a righthand side elevation, and Fig. 3 is a left- 0 hand side elevation, of Fig. 1. Figs. 4, 5, and 6 are different views of my improved manner of pivoting the intermediate flies. Figs. 7 and 8 are respectively end and side views of the creasing-knife which operates between the cyl- 3 5 inders. Fig. 9 is a view of the creaser on the intermediate fly. Figs. 10, 11, 12, and 13 are other detail views.

I11 the drawings, a is the frame-work upon which the folding apparatus is mounted. The

0 unfolded sheet is laid on the folder, covering the large and intermediate flies, cylinder, and raised portions a and a of frame. The large fly consists of the inner bar, Z, pivoted to the frame-work a, the outer bar,- I), and the cross bars or slats b c is the intermediate fly, occupying one-half of .the remainder of the frame a, and d is the smaller fly adjacent to the fly 0. In the remaining space, about centrally located between the raised portions a and a are the revolving cylinders e e.

The manner of reciprocating the large fly b b is as follows: f is the main shaft secured longitudinally in the frame-work 0. Upon this shaft is the bevel gear-wheel f which .intermeshes with the bevel gear-wheels f f, secured, respectively, to the transverse shafts f f. f is the sprocket-wheel by means of which the main shaft f is revolved. At the outer end of the shaft f is keyed a pulley, f having a segmental gear, f projecting outwardly from its periphery. Upon the corresponding outer end of ,the pivoted bar I) of the large fly is the segmental gear f Upon the outer end of the shaft f 5 is a segmental gear, f and upon the corresponding end of the pivoted bar 6 is the segmental gear f. In reciprocating the large I fly the motion of the shaft f is communicated to cross-shaftsfif and the segmental gear f 8 upon shaft f first engages with the gear f upon the bar b,which has the effect of turning the fly b I) over upon the'intermcdiate flies and cylinders. It is instantly turned back to its normal position by the succeeding engagement of the gear f upon shaft f with the gear'f upon the bar I).

The intermediate and small flies, c and d, are reciprocated as follows: The inner bar, 0, of the fly c is pivoted in the frame-work a, and has at its outer end the partial gear-wheel (See Figs. 1 and 10.), In like manner the inner bar, d, of the fly d is pivoted in the frame-work, and has at its outer end the partial gear-wheel (2. Upon the main shaft f is rigidlykeyed the arm g, having the inner segmental gear, g, with outwardly-extending teeth, and the outer segmental gear, g, with inwardly-extendingteeth, the two segmental gears just described being adjacent and concentric. As the shaft f revolves, as indicated by the arrow in Fig. 10, and carries with it the arm 9, the outer gear, 9 engages with the gearwheel 0 upon the fly c, and turns it over upon the small fly d and cylinders. 'As soon as this action is completed, the inner gear, 9, instantly engages the gear-wheel c and turns the fly 0 back to its normal position. As the shaftf still further revolves, the outer segmental gear, engages with the partial gear (1 upon the fly d, turning it over upon the cylinders e e, and the inner segmental gear, 9, engaging with the gear-wheel d, serves to turn the fiyd upper surface of the folder.

back to its normal position. The operation of the several flies in the order described is continuous, and the printed sheet, which is first laid upon the upper surface of folder, (composed of fly Z) I), fly c, fly (7, cylinders e e, and raised portion of frame acfl) is creased at in nor line of bar 6 and folded over upon the flies c and (7, cylinders e c, and raised portions of frame a a Creaser I) in large fly I) I) creases paper at inner line of bar 0. It is next folded over upon the fly 1?, cylinders e c, and raised portions aa" by the fly c, and refolded upon the cylinders cc and raised portion aa" by the fly d. Arranged centrally across the fly 0 is a creaser, 0, herein shown as pivoted in the bar 0, (see Fig. 9,) which serves to crease the sheet as it is laid upon the fly (l, cylinders c e, and raised portions a a preparatory to being again folded.

In order to further fold the sheet by passing it between the cylinders c c, I have arranged the following device upon the fly (7, (see Figs. 1,7, and 8:) h h are two inwardly-exten(ling arms of the bard. At each of the ends of these arms are pivoted the double sets of metallic straps h h and If If, and to these straps is pivoted the knife 71. \Vithin the knife 71 is the curved slot 7i,which ineloses the rod 71', passing through the ends of the arms /1 ll. This slot it limits the throw of the creasing-knife it as the fly (l is reciproeated back and forth. hen the fly (l is in its normal position, as shown in Fig. the edge h of the knife is flush with the surface of the fly; but when the fly is thrown over upon the cylinders c c the knife hi assumes the position shown in Fig. 8, and lies between and below the upper level of the cylinders c c. The action of the knife 11, as just described, causes the partially-folded sheet to be forced between and in contact with thein wardly-revolving cylinders c c, which carries the folded sheet below the same, dropping it upon the endless band or carrier 7:, and it is thereby carried to the point desired. 5elow the arms h h are the extensions or hangers h h, carrying the cross-piece h \Vhen the knife h is in the position shown in Figs. 1 and 6, it lies between. these hangers and upon the cross-piece 7LT. The lugs h 71. upon the knife h serve to break the hlowof the knife in both extreme positions. This endless band k is operated. by being passed around the pulley 7;, which is revolved by the belt k passing over the pulley k upon the shaft f". The foldingcylinders c c are revolved in opposite directions by the driving-belt 7, which passes over the pullcyf upon the shaftf and under and over pulleys Z and Z upon the cylinders c c.

In Fig. ll. is shown the manner of securing the slats of the flies to the pivoted bars, such slats I)' being rigidly fixed within the square sockets I), cast integral with the bar I). The pivoted bars a and d of the flies e and (7, when in their normal position, lie flush with the It is .lltwtSSZtly, for accurate iblding, that these bars should be slightly raised upon their inner ends as the flies fold the sheet, so that they will lie flush with the surface upon which they fold the sheet. I have accordingly arranged the following construction for effecting this purpose, of which on (see Figs. 4, 5, and 6) is a plate pivoted at in. in the frame-work (I. At its outer end isthe downwardly-projecting extension m", having the curved slot in. m is a screw, which passes loosely through the slot m and into the frame (a. Underneath the plate in is the socket of, between which. and the framework a is the spiral spring in. At the outer end of the pivoted plate on is pivoted the inner end of the bar 0 of the fly c. c is an inwardly-extending lug upon theinner end of the pivoted bar 0, and e" is a steel cross-plate secured to the frame a. Before the fly c is turned to fold the sheet it lies flush with the upper face of the frame, the lug c lying under the plate 0 \Vhen the fly c is turned in the operation of folding the paper, the lug 0 passes out from under the plate (5, thus permitting the springpresscd plate m to rise, carrying with it the pivoted bar 0 of the fly to such a raised position. that the paper can be properly folded. \Vhcn the fly c is turned back, thelug eis again forccdin under the plate c returning the fly to its normal flush position. The fly (l is likewise arranged in a similar manner. The sprocket-wheel f, for operating the folding apparatus, .rcsts loosely upon the collar 21, rigidly secured to the shaftf. The hub of the s )rockct-wheel f is provided with the recess '11, within which rests the dog a, between which and the collar w. is the spiral spring a, which operates to keep the end of the dog a in the recess a, so that in the positive rotation of the sprocket wheel f the collar a and shaftfis turned, operating the folder. \Vhen the direction of revolution is reversed, the dog a slips into its recess 1/ in the collara, and the shaftf docs notrewilve.

As a separate applicationis required for the peculiar construction within the hub of the sprocket-whecl just dcscribml, I hereby reserve the right to make such construction the subiectanatter of another ap 'ilication to be subsequently filed by me.
